[root@vmrac1 ~]# ocrcheck -local
Status of Oracle Local Registry is as follows :

Used space (kbytes) : 2728

------------这里我们再来看下ocr 的配置信息 ，配置文件在Linux环境下位于 /etc/oracle/ocr.loc
[root@vmrac1 ~]# cd /etc/oracle
[root@vmrac1 oracle]# ls
lastgasp ocr.loc ocr.loc.orig olr.loc olr.loc.bkp olr.loc.orig oprocd scls_scr setasmgid
[root@vmrac1 oracle]# more ocr.loc
#Device/file getting replaced by device +FLASH
ocrconfig_loc=+CRS
ocrmirrorconfig_loc=+ARCH ----------新添加的 ocr 镜像组
ocrconfig_loc3=+DATANEW
ocrconfig_loc4=+FLASH
local_only=false
[root@vmrac1 oracle]# more olr.loc
olrconfig_loc=/u02/app/11.2.0.3/grid/cdata/vmrac1.olr
crs_home=/u02/app/11.2.0.3/grid
-----------这里处理添加新的ocr外，我们也可以替换老的 ocr dg：
[root@vmrac1 oracle]# ocrconfig -replace +ARCH -replacement +FLASH
[root@vmrac1 oracle]# ocrcheck

---------------------注意：当 只有一个 ocr dg 时以上命令会报错：
[root@vmrac1 oracle]# ocrcheck

[root@vmrac1 oracle]# ocrconfig -replace +CRS -replacement +ARCH
PROT-28: Cannot delete or replace the only configured Oracle Cluster Registry location
[root@vmrac1 oracle]#
正确做法：
如果当前的ocr 少于2个 ，则上述ocr 的替换命令会出错
如果只有一个ocr 时我们可以先添加一个ocr ，再删除原来的ocr
# ocrconfig -add new_OCR_location
# ocrconfig -delete current_OCR_location
